INVENTORS: RUDOLF HELLER and WALTER SCHINDLER INVENTION: ARRANGEMENT AT A STAND FOR AN OPTICAL OBSERVATION DEVICE ABSTRACT OF THE DISCLOSURE An arrangement at a stand for an optical observation device, especially for a surgical microscope, containing a stand which essentially comprises an upright column or stand at which there is pivotably mounted an arm member for pivotable movement about a horizontal axis. There are further provided a support arm, a number of rotary and brake bearings and a hinge parallelogram at which there is suspended the microscope or the like. At one end of the arm member or arm there is arranged a guide lever and at the other end a weighting disk as well as a brake bearing at which there is secured a rod carrying a counterweight. The guide lever and the rod are operatively connected with one another by means of a thrust rod extending parallel to the arm member. This arm member is arrestable and positionably fixable at the stand column by means of a bolt member insertable into the weighting disk and radially penetrating the column body. The support arm is arrestable and positionally fixable at the guide lever by means of an element inser- table into the support arm and arranged at the guide lever.
